"The Ultimate Art!! " (究極芸術!!, Kyūkyoku Geijutsu!!) is chapter 362 of the original Naruto manga.

Summary

With Deidara defeated, Sasuke asks him where to find Itachi. Deidara refuses to give in and claims to still have some explosive clay left, but Sasuke does not believe him. Angry that an Uchiha is once again looking down on him, Deidara promises to prove his "art" superior to the Sharingan. Sasuke deactivates his Sharingan, no longer needing them, pushing Deidara over the edge. Apologising to Tobi, Deidara uses his C0, intending to blow himself up to take Sasuke and everything else in a ten kilometre radius with him.
